To ALL wHoM 1T M AY.' ooNoEnN:

Bc it known that we, HENRY FELTHOFF and LUCAS D. TINGLEY, of Prince William, in the county of Carroll, and State of' Indiana, have invented a new and useful Improvement in Drain-Tiles; and we do hereby declare that theI following is a f ull, clear, and exact description of the construction and operation'ot` the saure, reference being had to the accompanying drawings,'making a part 4of this specifica-tin, in which- V Figure 1 is a plan'view of mould and tile. l l l Figures 2 and 3 are -transversesections of the upperand lower moulds, with tiles shown therein.`V

Figure 4 is a transverse section ot' .the upper Vand lower tiles, shown as put together to form the drain.

` Like letters in the figures ofv the drawingsind'icate like parts.v

Our improvement relates to a new and improved tile, and method of making,d'by mouldingnthe same, it being designed for thc purpose of building drains for conveying water under the surface of the ground.

It consists of two moulds, in each of which'is moulded a.ti1e of such form that the grooves and joints,

thereof are in shape or construction the exaetieouverse ofeaeh other,Y in order that when the tiles moulded therein are placed as designed to form the trough, thejoin'ts or projections upon the one resting upon the earth t closely into the grooves ot' the one upon it, while .those of the latter are similarly adapted to the former,-

whereby they thus conjointlylform a quadrilateral object, having a smooth exteriorgand iuteriorlsurface, while forming a trough for the conveyance of water, which trough lis incapable of being displaced or disarranged by lateral pressurebeneath the earths surface, andwhich tiles, when moulded, are like burnt brick in a brick-kiln.` I .A represents the trough or drain, formed by the union of two tiles, whosejoints or projections fit into the.

grooves or interstices of. each other. i

B represents mould for upper tile,.having grooves or interstices therein, of such correspond-ing shape and size as that the tiles moulded'therein, groove into and :closely t those formed in the' mould C.

G represents a mould for lower tile, having grooves orjoints therein of s'uch conformation and size as to be adapted for gro'oving into and closely tting those tiles formed in the uionld B. l

B and C represent the tiles joined together. P represents an' aperture in the lower tile, formed by the pina in the'meuld C, through which'water enters into the drain, after having descended from the surface of the earth, or from a greater altitudo'than Vthat where the drain is laid in the earth. 5 And thus it ilows into said drain along its entire length, and is in like mannerV carried olf. i Y v` l b represent elongated slits in the moulds, which'are Adesigned to admit theair in the process ofmoulding the tiles. i 4 v The advantages which this tile (furthe construction et' drains) presents over-'those hitherto' used, are, first, that they can be easily opened for the purpose of removing the sediment or dirt which often colleetsin'vdrans, and, liy choking-.them up, defeats the objeet'for which they were laid.

And again in the. facility with which, having performed their oliec at oncpoint, they can be removed to another. Besides which, as drains have hitherto been constructed, theyhave merely received thewater yat the point of their greatest altitude, and conveyed it to that of'their greatest depression, without rendering any service whatever along the routethrough which the drnirrmay have been laid, whereas, drains huilt of` tiles constructed as aforesaid, are formedI to receive the water' through the apertures therein, along their entire length, acting'thus as constant drains to the land through which they extend; and further,- thc water will no't only get,`

into the drain through the apertures, as just above remarked, but will permeate through thejoint's and pores of the tiles, and thus fulfill a threefold oficc oi' accomplishing the draining of the land in a very desirable mann'er.

Having thus fully described our invention, whatwe claiin therein as new, and desire to secure by`Letters The arrangementof the moulds B and C with pin'y and elongated slits 6,6, s'ubstantiallyin tho n iannel.-

and for the purpose as herein shownand described.
